FLouRj-MILL.

SPECIFICATION forming part of Letters Patent No.. 410,879, dated September 10, 1889.

Application filed March 28, 1889.

To a/ZZ whom t may concern:

Beit known that I, NICHOLAS CORNELIUS, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Flour-Mills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure I is a side elevation illustrative of my invention. Fig. II is atop view. Fig. III is a detail section showing the manner of adj usting the roller. Fig. IV is a horizontal section taken on line IV IV, Fig. V. Fig. V is avertical section taken on line V V, Fig. IV; and Fig. VI is a view, part in section and part in elevation, illustrating the cylinder and roller on an incline or out of a vertical position.

My invention relates to that class of flourmills in which is employed a cylinder and an eccentrically-arranged roller within the cylinder-as, for instance, as shown in the patent granted to Clayton S. Wenger on the 5th day of October, 1880, No. 232,863, and the patent granted to Henry Stanley, Emil O. Teuscher, and myself on the 15th day of November, 1887, No. 373,342.

My present invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, 1 represents a cylinder having a lower head 2 and an upper head 3, connected by tie-rods 4, which also pass through lugs 5 on upper and lower rings 6, whichA fit around the cylinder, the latter being recessed, as shown at 7, Fig. V, to receive the rings. The head 2 may be placed on supporting-legs 8, as shown in Fig. I.

Within the cylinder is an eccentrically-arranged roller 9. (See Fig. IV.) This roller is provided with journals 10 on its respective ends, which fit in boxes 11, the upper box being held between flanges 12 onthe head 3, and the lower box being held in a guide 13, secured to the legs 8. The boxes are made adjustable in their supports for the purpose of adjusting the roller to or from the cylinder; and as a means for adjusting them I have shown threaded rods 14, secured to the boxes (see Figs. II and III) and having nuts 15 on their outer ends, so that by tightening Serial No. 305,096. (No model.)

or loosening the nuts the boxes, and accordingly the roller, may be moved in or out.

To give an elastic effect to the roller,I ein ploy springs 1G, surrounding the rods 14, between the nuts and the supports of the sliding boxes. These are illustratedv in Figs. I and II.

One of the journals of the roller 9 is provided with a driving-pulley 17, and the central portion of the cylinder 1 is formed to re ceive a belt, and the manner of driving and controlling the operation of the roller and cylinder is the same in this case as fully described and explained in the patent last referred to.

2O represents a conveyer for delivering the grain between the roller and cylinder. My preferred manner of constructing this is illustrated in Figs. IV and V, and consists 0f a casing 2l, narrowed down to a point 22 at its forward end, as shown in Fig. IV, and into which the grain is delivered from a chute 23. Vithin the casing are a number of inclined ways or partitions 24, 25, and 2G, which extend farther back toward the rear of the eas? ing from the` top toward the bottom. The grain falling onto these and also onto the bottom 27 of the casing, as illustrated bythe arrows in Fig. V, is delivered to the action of the roller and cylinder uniformly.

Other forms of conveyers inightbe designed for accomplishing the same purpose.

28 represents a brush for cleaning the outer surface of the roller and the inner surface of the cylinder.

'Ihe stuff as it is ground may fall onto a discharge spout or conveyer 29 (see Fig. IV) and is delivered into a suitable receptacle.

The gist of this invention consists in arranging the roller and cylinder out of a horizontal position, either into a vertical position, as shown in Figs. I, IV, and V, or into a position inclined from the horizontal, as shown in Fig. VI, the object being to have the parts at such a pitch toward the vertical that they will be self-delivering and avoid the necessity of adischarge-conveyer.
